(GRANTED UNDER THE PRGVISINS F THE ACT 0F MARCH 3, 1921, 41 STAT. L., 1313.)

To all whom t may concern.'

Zen ot' the Free ccitate Voi lrussia, in the `German Republic, residing at Neuruppin, in the lT ree State otlrussia, Germany, have invented improvements in lnking Devices 'for lype .Printing Apparatus (for which l have tiled application in Germany Apr. 19., i918, Patenti-lo. 309,848); and l do hereby declare the following to be a full, clear, and exact description of the saine. l

'.lhe invention relates to a device :for inkinp; the'types oit such. type printing apparatus, for instance typewriting` machines, in which no ribbonsare used but the types inlred by direct contact with an ink roll. iiocordino; to the siinplest 'modification devices of suchv kind are so constructed and used that the printing apparatus is provided with a casing for the ink roll, in which said rollsupplied with ink is` arranged. i/Vhen the inl; is consunied the `roll is reinoved and replaced by another inlable roll.

`. rllhese apparatus. had the disadvantage that `the troublesome .and dirty work of taking out the used roll and replacing the new roll had toy be carried out .relatively otten. i

Endeavours have been inade to obtain a longer duration of the ink roll by positively pressing' the latter against an inl: cushion after each contact with a type. As however always the sanie portion oit the cushion is niet by the type this method is oi'f little success only. This method has inoreover the disadvantage that only a small part of the inked surface ot the ink cushion is used. To .supply the inl; cushion. with lresh ink however just as troublesome and dirty as the change oi the inlr roll of the older construction mentioned above which. is much more simple.

According to iny new invention the dis advantages ot the known constructions are obviated by the use of inea-ns which allow a inuch more simple and much better use than is the case when employing the well lniown devices mentioned above. The use of the present device makes soilingl of the hands manner et a lanip Wick and adapted to supply ink to the ink roll when 'the latter is pressed into contact with the wick.

The arrangement may of course be such that the type is brought into contact with the wick directly, so that the type itself is provided with ink troni the wick. in inost cases however, this arrangement is not advantageous since the type impressions are not as uniform and strong as when the inl;- inp; roller is provided.

When after extended use of the wick and the inl; supplied. to the latter is consumed, the wick is advanced by a feeding device and the consumed portion of the wick may be cut away by scissors. ln order tol further eX- tend the lite of the wick, the arrangement may be such that the wick is viinniersed in a l reservoir filled with the liquidinl.

The invention is shown in the drawings bv Way ot example.

caoutchouc or the like is placed upon a pin l vand' this `roll carries a cylindrical inl; cushion 3. A lever d, carrying the pin 1, is inounted upon a stud which is secured to the traine of the device by ineans ot a thread 6. The latter carriesy a tubular sleeve 8 in which is arranged a cylindrical wick 9. rllhe wick 9 is nioved by the turnino; ot a disc 10 and its end to be ted it'oi- .later use is immersed into a reservoir lled with ink which is however not shown in the drawing.. The feeding' device of the' wick is well known from the oil lamps and the lilzeand a shaft ll is provided which caru ries a toothed wheel. The latter projects through a slot 13 into the sleeve 8 and en: i

gages the wick arranged in said sleeve.

When the type 14C is moved to the printing" position it first inipinges upon the roll shaped ink cushion 3 and is supplied with ink from the latter. Then the type drives' the cushion in front oi it inutil, it escapes,

laterally freeing the 'way for the type to contact against the paper' to be printed. The lateral movement of the ink roll is effected by turning` of the lever 4; so that the cushion 3 by Way of the dotted lines shown in Fig. 1 advanced to the sleeve S until it comes into contact with. the Wick 9 Whiclris at this portion uncovered by a slot 15 of the sleeve S.

During this time the type 1d has been moved into contact with the paper upon the platen and effected the printing; whereupon it is returned to the position of rest. The roll 2 also returns under the action of a coiled spring 16. One end of the spring is arranged around the sleeve 18 and is eX- tended to a nut 16 firmly secured upon the thread 6 of the stud 5. A. second springl1 .forms a limitstop for the ink roll 3 and this stop may leasily be removed sideways.r The arm 19 carrying the holder for the ink roll is soldered to the sleeve 8.

Having now described and ascertained the nature of my invention and the manner in Which the same is to be performed I now decla-re What I claim and desire to secure by Letters Patent of the United States: Y In a machine for printing from types the combination of an ink saturated Wick, a tubular open ended sleeve enclosing and guiding said Wick and having a llongitudinal slot, means for feeding ysaid Wick to bring a fresh portion thereof into the said slot, a rotatable and oscillatory inking roller in parallel position vwith regard to the 'Wick containing sleeve, and types, ythe inking roller upon being struck by a type being oscillated to come in contact With the Wick at said slot to receive ink from the Wick.

2. In a machine for printing from type, the combination of an ink saturated Wick; a casing for guiding said Wick; an inking rolle-r; a pin on which said roller is rotatably mounted; a rotatably, mounted member on which said pin is mounted; a spiral spring on said member; and types7 said member carrying the inlring roller being rotated against the action of said spring when a type strikes against said inking roller to move the inking roller into contact with the Wick to receive ink therefrom, the spring acting to return the member with the rollerV to normal position.

3. In a machine for printing from type, the combination .of an ink saturated Wick; a casing for guiding said Wick; means for feeding tlie Wick; an inling roller; a pin on Which said roller is rotatably mounted; a rotatablymounted member on which said .pin is mounted; a spiral spring on said member; and types,said .member carrying the Linkingroller being rotated against'the y action of said spring` when a type strikes against said inking` roller :tomovexthe ink- `ing -`roller into Vcontact VWith lthe Wicky to receive ink therefrom, `the .springacting toret-urn themember with the roller to normal position.

f1. In a machine for printing from type, the combination of an ink saturated Wick; a casing for guiding said Wick; an opening at onecndvof said casing; means for feeding said Wick to bring ya fresh portion thereof to said opening; an inking roller; a pin on which said yroller Vis rotatably mounted; a rotatably mounted member on which said pin is mounted; a spiral spring on said member; and types, said member carrying the inking roller being rotated against the action of said spring7 Whena type strikes against said inking roller, to move said roller through said opening `into contact `with the Wick to receive ink therefrom.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing Witnesses.
